Sample Preparation:

Sampleprep ID:	SP000796
Sampleprep Summary:	Dried black soybeans were ground into a fine powder and sieved through a screen with a 55 mesh count, then 40 mg of the powder was mixed with 70% aqueous methanol (4mL, 1% HCl) containing 1.5 μg/ml phlorizin as an internal standard and sonicated for 30 min. The mixture was kept for approximately 16 h at room temperature in the dark.vacuum.Supernatants were filtered through a 0.20-μm syringe filter and freeze dried then reconstituted with 0.5 ml of 50% aqueous methanol for LC-MS analysis.
